9 Claims.

This invention relates to shaving brushes and it particularly relates to a sanitary shaving brush, which, except for a few drops of water, contains all the ingredients necessary to whip up a creamy lather in a surprisingly short time, but just the same will in that short time soften even a very tough beard so as to always give the user that comfortable feeling so much enjoyed when after a shave he pats his face with his 30 hand and finds it really smooth without being annoyed by the itch caused by too much scraping to remove tough hair.

Every man knows that it very often is a most unpleasant task to work up a sufiiciently creamy lather, which may be due to various reasons, for instance, lack of warmwater,.but mostly is due to an insufficient quantity of soap on the face. This is particularly the case in the morning when in a hurry to get to work on time the shaving is done in a hurry so that the affair is abbreviated most unsuitably with unpleasant and unsatisfactory results, one of them being that the hair is not properly treated and causes inflammations of the skin by ingrowing hair, or that the roughened skin attracts disease germs so as to invite and to cause even more serious skin diseases.

It is with the wish to give these people relief by providing them with a modern shaving brush, which abbreviates the time of working up the lather, always supplies to the face the absolutely necessary amount of soap so as to give the user an absolutely refreshing feeling, protect them simultaneously against infection, and is so arranged in its construction as to be destroyed after one use so that, for instance, it cannot be used over again on the face of another customer.

With these ends in view the invention resides in our new shaving brush illustrated in the accompanying drawing, in which Figure 1 is a perspective view of our new shaving brush, part of the brush being broken away to show the inner arrangements of the parts, the porous rubber shaving brush having a handle or cap mounted thereon at one of its ends in such a way that in a short time after its use the cap automatically removes itself from the porous rubber body of the brush; and Figure 2 is a fragmentary perspective view showing the rear part of our new brush having a modified form of a cap or handle, Figure 3 shows likewise a handle destructible by water.

Referring to the drawing, the numeral 1 denotes an elongated piece or body of sponge rubher which may be of any suitable elongated form of round, oblong, or square cross section. It depends, however, very much on the convenience and conditions under which the raw material, namely sponge rubber is manufactured as to which form is the most economical and in View of the constant changes or variations in this art we shall not restrict ourselves to any particular form; at the present time we find the form of a rectangular prism very suitable, also on account of the convenient way in which these prisms may be cut and provided with the handle, described further below, and may be wrapped for delivery to the trade.

At one of its ends means in the form of a cap 2 of prismatic, annular, oval, or other suitable shape and made of transparent or opaque material, such as paper, paste board, papier mach, celluloid, cellulose acetate, casein-compounds, or rubber, bakelite, urea-formaldehyde condensation products and similar natural or synthetic materials, or compositions nowadays so much in vogue for the manufacture of novelties, is arranged around body 1 to serve as a handle for the body of sponge rubber to be used as a brush. From an inspection of the drawing it will be noticed that this cap or handle 2 is arranged approximately at of the whole length of the body 1 from its right end.

The pores of the sponge rubber are denoted by numeral 3.

Another desirable feature of our new brush is the cavity l which extends for some length, for instance, approximately one quarter of an inch, into the body 1 of the shaving brush.

In pursuance of the purposes of the invention a considerable part of the body 1 is filled or impregnated with a cleansing compound 5, of which soap is the main constituent. A description of the various steps required to impregnate the body 1 is not given as it is not essential to the invention forming the subject matter of this present application.

In using our shaving brush the same is dipped into water so as to form a soap solution by the action of the water on the cleansing compound 5. Then the wetted body 1 is rubbed all over the face and soon the formation of the lather begins. In passing the wetted body 1 over the face the face is patted with the brush so that by the compression of the body 1 in the direction of the face the air in the pores 3 is pressed into the lather, and while this is continued new air is constantly absorbed by the pores 3 and pressed into the latherywherein the air is finely distributed and thus contributes to generate a creamy lather which is most helpful for a successful shave.

Theivolume 'of air introduced by the aforesaid steps intothe lather is increased by the function of thecavity 5, which during the handling of the brush fills with air and upon the compression of its body 1 can only escape into the lather.

From an inspection of the. drawing it is evident that the porous rubber body is inserted into the cap or handle 2, but that it terminates shortly before the top or rear wall of said cap 2, the interstice being filled with a chemical material, or mixture of substances 5, and a partition '7, made of a porous substance, suitably of paper, particularly of a highly bibulous character, interposed between the chemical substance 6 and the adjoining rear end of the body 1. The rubber body 1 is slightly compressed when it is inserted into the cap 2. It is here by this cooperative engagement of body 1 and cap 2 where one of the essential features of the invention comes in.

The chemical material or mixture of substances 6, may consist of a mixture of a carbonate, such as an alkali metal or alkali earth metal carbonate, and a dry acid, or an acid salt, such as tartaric acid, or sodium-bisulfate or any other non-poisonous acid capable of liberating the carbon dioxide gas from aforesaid carbonates as soon as intervening water causes a reaction between said carbonate and acid substance, thereby liberating the carbon dioxide in gaseous form. The partition 7, being interposed between substances 6 and the porous rubber body 1 and engaging the inner walls of the cap 2, forms a substantially gas tight though slidable partition, which on account of its absorptive or bibulous character allows the water to pass on to the chemical substance 6 to cause the same, or its component part, such as one of the aforesaid carbonates and one of the acids, to react with each other and to generate carbon dioxide gas.

On account of the porosity of the rubber body 1 the water, used for producing the lather, will travel towards the rear end, pass through the partition 7 and bring the substance 6 to reaction, thereby generating sufficient carbon dioxide gas to press the partition 7, which even in the wet state is resistant enough to the gas, and the rubber body 1, in front of it, out of the cap 2.

By this automatic removal of the body 1 from the cap 2 one of the first requirements of sanitary barber service is fulfilled, namely, that the barbers will not use the same brush again for another customer, for investigations have shown that the barbers refuse as a substitute for the old fashioned shaving brush any mechanical device, which is devoid of a handle, as in such case, among others, they are liable to scratch the face of the customer with their finger nails.

It is, of course, understood that as to the nature of the chemical material, or the mixture of substances 6, we are not restricted to the application of the chemicals mentioned above, but that any other substance, causing by interaction with water a gas of harmless nature, may be applied for the separation of the handle from the porous rubber body 1 after the brush in its original has once served its purpose.

That the problem may be solved by various mechanical arrangements is illustrated by Figures 2 and 3, by which it is shown that a hollow filament 8, made of absorptive paper, containing particles of the chemical material fi, may be wound around the rear end of the body 1 so that it, analogously as described above, absorbs water and the carbon dioxide, generated by the action of such water upon the material 6, gets voluminous enough to break the moistened paper of the filament 8 and thus separates the handle from the body 1.

The various windings of the hollow filament 8 are separated from the front end of the brush by a ring 9, made of rubber, celluloid, or other similar opaque or transparent waterproof material, which is to prevent the water from prematurely acting on the substance 6 within the filament 8.

Aside from the forms of the handle as de scribed above the handle may also consist simply of a cap 10 made of cellulosic materials, such as finely divided paper fibers subsequently pressed into the shape of a cap with the help of small quantities of a water soluble binder, such as starch, dextrine, gum arabic, and like substances, which will dissolve when the water from the lather reaches it and acts upon it. Also water soluble substances, like crystalline sodium chloride, sodium sulfate and like harmless substances may be added to it in finely divided form and upon their dissolving by water the collapse of the handle will be accelerated.

The mixture of fine cellulosic particles and a fine powder of a water soluble binder may be provided with a mixture of water soluble substances which by interaction with water develop a gas, for instance, as described above, carbonic acid.

1. A new article of manufacture, a sanitary shaving brush consisting of a porous rubber part and a handle composed of water soluble material superimposed upon one end of the same.
